Starting at a new lab without the best background in genetics and this was soooo helpful! thank you !

I like how you give really great, thorough introduction and that you explain the paper really clearly with many visual aids. :)

@@TheSheekeyScienceShow You really made this complicating thing easy to understand for me. Thanks a lot. Writing a research paper on genome editing, and I'm using Prime as the Future! Very interesting and promising!

Great review! Also worth mentioning that they designed sgRNAs that match only the edited strand to minimize double-strand DNA breaks (PE3b); this way nicking of the non-edited strand occurs after edited strand flap resolution.

That was really nice and well-explained. Thank you for sharing your knowledge and skill. Please make more videos like this.

Super good explanation! Thanks for the video and the references :)

Thank you so much for making this! A quick question, is the primer binding site in the linker region between the cas9 and the reverse transcriptase?

Excellent and easy to follow summary🎉

This is cool, thank you Eleanor, for the animated cartoon video, which helps a lot. BTW, what program you used for annotation and drawing?

Love this explanation!

So, in Prime Editing, that Cas9 attaches to the Target Strand, but edits the Non-Target strand?

Great explanation!

Why is SSBs "inefficient", your conlusion is the direct opposite of what other researchers say, namely that DSBs are inefficient, therefore SSBs er more efficient?

@TheSheekeyScienceShow

The purpose of prime editing is to make gene editing safe and efficient. Using wild-type Cas9 that induces DSBs has been shown to efficient but is not safe. SSBs are much safer and use a mutated version of Cas9 that cuts one DNA strand. SSBs are quickly repaired by the cell which does not provide sufficient time & interaction for the integration of the sgRNA/Cas9/repair template complex, hence very low efficiency - this was the rationale behind the whole paper and design of prime editing. I have personally tested and directly compared the editing efficiencies of WT-Cas9 (DSBs) and H840A-Cas9 (SSB) and in my set up WT efficiency was ~20% whilst H840A was

This is too complicated. I will stick with near PAM-less CRISPR, using HDR donor repair templates.
